Specification of Letters Patent. Application filed March 11, 1905. Serial no. 249,616.

I ,Patented Dec. 5,1905.

To all whom it may concerns I Be it known that I, LoRoN O. BURNHAM, a

. citizen-of the United States, residing at Clare,

in the county of Clare and State of Michi' an, have invented certain new and useful mprovements inTile-Making Machines; and I do hereby declare the following to be a-full,

clear, and exact description of-the invention,

such as will enable others skilled in the'art to which it appertains to make and use the same.

- My present invention relates to a machine for molding drain-tile and the like and the details of my invention will be hereinafter clearly set forth, it being understood that the preferred form thereof only is presented in this ap lication and that I wish to comprehend a substantial equivalents and substitutes fairly falling within the purview of my invention. a

My object, among others, is to fashion from cement or other material a'section of a tubeadapted as a drain-tile for use in culverts and many other purposes. v

In the accompanying drawings, made a part of this application, Figure 1 shows my invention complete ready for use. Fig. 2 is a longitudinal vertical section of parts of the invention, shown in Fig.1 as taken on line 2 2 thereof. Fig. 3 is a sectional view, of a por. tion of my machine, shownin Fig. 1 onthe dividing-line designated 3 3 in said view. Fig. 4 is a detail view of the inner member designed toform the inner surface of the tubin or section ofdrain-tileQ Fi 5 showsa slig tly-modified construction 'om that presented in Fig. 4 for'the same part. 6 shows a-slightly-modiiied form of base from that shown for the member illustrated in Fig. 4,. Fig. 7 shows the outer casing designed to cooperate with the member shown in Fig.6. Fig. 8 shows the casing in an opened position and designedtocooperate with the base shown in Figs. 4 and 5,- Fig. 9

shoWs aslightly-modified form of construction for the member 8, inasmuch as the u per end thereof is shapedso as to provide t e upper end of the tile produced with a reducedterminfal adapted to enter the flared or specially-shaped end of another section of tile with which it is designed to cooperate.

Briefly stated, my invention comprehends a suitable form of mold and convenient means for handling or controlling the molds whereby after the tile has been formed from plastic material it'may-be bodily lifted away Fig. 1

without injury and left to harden or dry, as the case may be, without liability to checking or cracking,as is common when articles formed from plastic materiala're left'to set or dry Without a reinforcing or shaping mold or holder.

Referring in detail to the .various parts of my invention, lIdesignates' the base member 65.. 'dicates the cross-bar cooperating with the of any preferred material and size, and 2 in-' base member and designed to suptiort the standards 3, upon the top of which secure the table or supporting member pro er, 4, i I

which is disk-like in form, as more cearly shown in Fig. 2. Designed to telescope with the standards is vthe'drum or outer casing 5, secured permanently to the carrier 6, which latter is provided with openings to loosely receive the standards 3, whereby the carrier may be readily raised and lowered by the controlling lever 7, pivotally connected to the lower side of the carrier, as between the ears 8 or equivalent means, the outer end of the lever being pivotally connected, as designated by the numeral 9, to the pivoted standard 10.

The lower end of the standard 10, it will be observed, has a pivotal connection with the end of the base member or platform .1, While the upper end is rovided with a recess'll to fit beneath the e ge of the casing 5 or carrier 6, so thatwhen the casing is raised to its fullest extent the end of the member 10 willbe moved inward in engagement with the lower edge of the casing, and said member 10 will thus reliably support the casing in' an elevated position, as will be clearly obvious by reference to Fig.1. It will furthermore be observed that I have securedto the carrier 6 the upwardly projecting shaft or guiding member 12, which fits 'loosely in a suitable a erture in the table or disk member 4 and a so enters loosely through an opening 13 in the bottom 14 of theinner mold 15, as clearly set forth in Fig. 2.

The moldproper consists of the inner oasing or member 15 and the exterior casing or jacket 16, and both of said members 15 and 16 are carried by the bottom section 14, above referred to, the member 15 or inner member preferably being permanently secured to the bottom and having a removable apertured cap'15 while the member 16 is removablyconnected thereto.

The bottom section 14 is designed normally to rest upon the table or support 4, and the aperture in the center thereof is IIO placed in registration with the aperture in the central portion of said table. It therefore follows that when the bottom 14 and molds carried thereby are placed upon the table the guiding-shaft 12 will enter freely upward through the said openings and into the apertures in cap 15 and will hold the bot tom and the cap in proper position.

The outer casing or member 5 is designed merely as a housing to better secure the molds in position and prevent them from casually slipping off ofthe table, and thereby lend greater rigidity and strength to the entire appliance.

Obviously any preferred shape may be imparted to the tubing formed by my improved molding process, inasmuch as the tubing-sections may be made square, octagonal, or round in cross-section by properly shaping the molds, as will be obviously clear.

It Willbe understood that a plurality of molding members 16 shall be provided for each machine, so that when one section of tubing has been formed it may be bodily carried away, together with the molds and the bottom section 14. The section 14 and member 15 are then removed, and the tile is left with member 16 to harden or dry and until such time as the exterior casing may be safely removed therefrom, and it therefore becomes desirable to provide means for quickly removing the exterior molding-casing 16, and I therefore prefer to split the same throughout one side, as shown in Fig. 8, so that the same may be readily expanded and lifted 1away from the molded member surrounded y it.

Any suitable means may be provided for holding the meeting edges of the member 16 in temporary approximationas, for instance, the latch 17 or the e uivalent thereof, said latches being designe to fit over into the recess 18, provided in a contiguous part of the edge of the casing.

In Fi 9 I have shown the casing 16 as provide with an inwardly-directed offset or shoulder 19 and with the terminal or flange 20 of reduced diameter. It is by this means that the end of the tiling may be shaped so that the extreme end thereof will be of less diameter than the body portion, and thus fit it to enter the correspondingly-shaped end of a contiguous tile.

In Fig. 3 I have also illustrated the outer member 16 as slightly modified from the construction illustrated in Fig. 2, inasmuch as an angular shoulder 21 is formed which imparts to the upper end of the tiling (designated by the numeral 22) an enlarged section, insuring that the next contiguous section will fit therein if the end is shaped as shown in the lower part of Fig. 3. With the form shown in this figure a cap 15 is arranged in the inner member 15 and extends laterally therefrom.

Obviously other shapes may be given to the ends of the tile by properly shaping the molds according to the shape desired.

Having thus fully described the construction of my invention, it is thought that the operation thereof has been made clearly apparent, though it may be stated that when it is desired to use the machine the bottom seetion 14 is placed upon the table member 4 so that the central aperture in the bottom will register with the opening, through which the shaft 12 is extended when the free end of the lever is raised, which will cause the exterior casing 5 to move upward and surround and support the exterior casing 16 and also cause the supporting member or lever 10 to move inward, so that the recess 11 would engage the lower edge of the casing 5 or the carrier 6, as the case may be, insuring that the casing 5 will be supported until the lever 10 is disengaged. After the casing 5 has thus been elevated, so as to surround the casing 16 and the interior molding member 15, the plastic material is entered so as to fill the annular space between the members 15 and 16, and after said space has been completely filled the member 10 is disengaged and the free end of the lever 7 lowered, which will cause a corresponding movement of the casing 5 and leave the molds 15 and 16 supported upon the table 4, which is carried by the standards 3, as before explained, The molds 15 and 16, with the contents contained therein, may be lifted bodily from the table and removed to a convenient point, after which the member 15 is removed and the tile left to set or harden in the member 16. The members .14 and 15 are then again placed on the table 4, a d a ter p ttim a ot er 16 11 261 16 in place therearound the operation just described can be repeated.

In order to show that the inner mold 1.5 may be easily removed from the newly. formed section or tiling or tubing, I will call. attention to .Fig, 5, wherein it will be observed that the mold 15 is split longitudinally upon one side and the upper edges thereof are designed to be drawntogetjher and see cured in this contracted position by a suitable latch or securing device 23, By then striking the up er end of the inner mold 15 it is withdrawn fi 'om contact with the new1yformed section of tiling, thus permitting the inner member to be easily Withdrawn therefrom. In like manner the latches or keepers 17 may be disengaged from the recesses 18 and the exterior casing easily taken away.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is i 1. The herein-described molding-machino for plastic material whereby the same may be held temporarily until set or partially dry, comprising a suitable supporting-base; standards carried by said base; an exterior hous- 5 an auxiliary lever 10 cooperating with the controllinglever and suitable collapsible molds adapted to rest upon said table and receive said centering device whereby when the controlling-lever is elevated the housing IO will be brought'to surround said molding appliances and secure them in their operative iplosition, all combinedsubstantially as speci ed and for the purpose set forth;

2. In a molding-machine the combination 15 with a casing; of a table, collapsible molds adapted to be supported by the table, means for moving the casing into position around the molds and a centeringdevice movable with the casing. I v

3. In a molding-machine the combination with a stationary table and a collapsible mold supported thereby and having apertures in the ends thereof; of a movable casing adapted to surround the molds and a centering device movable With the casing for entering the apertures in the molds.

I '4. In a molding-machine the combination witha table; of an inner mold-casing supported upon the table and having an a ertured bottom portion, a acket surroun ing the inner mold-casing, means for securing the jacket around the inner casing, a movable casing for surrounding the mold-j acket, a centering dev'ice movable with said casing and adapted to extend through the'bottom of the mold and means for operating the movable casing.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
